Absolute tool in Cardiff. Cuts up traffic, undertakes, bullies people. I saw him bully a woman with her children when he overtook cars stopped at traffic lights and forced her on to the pavement to avoid a collision. Wish I had a dashcam as I would report him to the police immediately.

You are, like most people who fail to indicate, dangerous to other road users and pedestrians. Unfortunately for the rest of us no action will be taken until you've killed someone or caused a crash and it's been caught on camera that you've failed to indicate.

I'm wondering what sort of response you'd have if some other nutter did exactly what you did but killed or badly injured one of your family?

There is no excuse - you are taught to use them to enable you to pass your driving test - if you failed to indicate you wouldn't be granted the privilege to drive
